A line contains the points
(-3,-7) and (1,5)
What is the slope of the line?
A.) 1/3
B.) -2
C.) 3
D.) -3
To find the slope of the line passing through the points (-3, -7) and (1, 5), we can use the slope formula:
m = (y2 - y1) / (x2 - x1)
Let (-3, -7) be (x1, y1) and (1, 5) be (x2, y2).
m = (5 - (-7)) / (1 - (-3))
m = (5 + 7) / (1 + 3)
m = 12 / 4
m = 3
Therefore, the slope of the line passing through the points (-3, -7) and (1, 5) is 3.
So, the correct answer is:
C.) 3
